Referring to the drawings in which like reference characters indicatelike parts, 1 designates-the cabinet or outer housing of our novelbeverage dispensing apparatus, being any suitable shape and formed of aplurality of panels 2, and a front or main panel 3, upon which aremounted the various exposed parts of the apparatus, such as the sightglasses 4 and `5;vthe serving door 6; the trap door 7 leadingtoa wastecontainer for the disposal of all the Waste or used cups; the series ofcoin .slots 8; the correponding series of operating handles or knobs 9;and the series of name plates 10, corresponding to said series ofcoinslots and op'- erating knobs, for designating the particular flavor ofdrink corresponding. to any `particular coin slot and operating knob. A

. Within the cabinet l, are disposed the operating parts of ournoveldevice, land 1n particular, there is located, preferably in one ofthe rear corners of the cabinet, a steel storage tank or gas bottle 11,of the usual commercial type, containing a supply of carbonic acid gas,or carbon dioxide, under pressure, and which is hereinafter referred toas the gas. The refrigerator tank 12, located at the bottom of thecabinet 1 and occupying the major portion of the bottom area thereof, isprovi-ded for refrigeration of the water A used to prepare thecarbonated water :for the mixed beverage, and may also, if so desired,be used for `storage of the water as Well; that is, a mixture ofdrinking water and pure ice may be placed into the tank 12, and theWater may then be drawn into the carbonating battery directly from suchice and water mixture. If desired, the tank 12 may be merely utilized asa refrigerating chamber, the drinking water being supplied' from thewater mains through suitable pipes. In either event, the carbonatingbattery 13 is disposed within said refrigerating chamber 12, therebyeffecting a cooling of the water in either case, as it passes throughthe battery 13.

The series of syrup tanks 14, corresponding to the series of coin slots8 and operating knobs 9, are positioned in the uppermost part of thecabinet 1, extending rearwardly alongside of each other, and supportedby suitable brackets l15, which in turn are secured to the rear face ofthe` front panel 3. The cup dropper 16, of any suitable construction, isalso mounted upon the rear face of the main panel 3, as shown, inFigures 5, 9 and 13, and is provided with the glass reservoir orcontainer 17 for the storage of a `quantity of nested paper drinkingcups. It will be noticed that the glass reservoir 17 is positionedbehind and in alignment with the sight glass 5, thereby permitting thevisual inspection of the container 17, for the purpose ofascertaining,the quantity of paper cups contained therein at any time. The paper cups.18, as they are released from the cup dropper 16, are jthenv guided bymeans of the guideway 19 into a cup support 20, positioned yupon theserving platform 21, which is carried by the hinged serving door 6.

The two end frame members or plates 22 and 23, also secured to the mainpanel 3, are provided as supports for the series of ejectors or pumps24, corresponding to the series of'syrup tanks 14, and also support themain shaft 25, and thecontrol valve and mixing chamber casing 26.

Referring to the drawings more in detail, our novel mixed beveragevending apparatus is adapted to carry 4out a cycle of operations asollowsz--upon .inserting a' coin into any one ofthe series of-coin slots8, the corresponding knob 9 andhence the corresponding operating lever27 is released from its normal or' locked position, by meanaof the coincontrol mechanism shown particularly in Figures 2 to 4 inclusive.4 The`operating lever 27 is loosely mounted upon the main shaft 25, andcarries .a lug or dog 28 adapted to encounter a suitable pin or otherprojection 29 carried by said shaft. By suitably adjusting the relativepositions of the dog 28 and the pin 29, the lever 27 can be made toengage the control shaft 25 at any desired pointin its downward travel,which adjustment, as will be brought out more. in detail hereinafter, isessential to the proper timing of the control valve, syrup pumps and cupdropping device.

The pivot bolt 30 is mounted upon the lower extension of the lever 27 inan adjustable manner, in thefslot 31 and below the main shaft 25. Thebolt 30 carries a connecting rod 32, which is in turn pivotally mountedat its other extremity upon the wrist pin 33 of the piston 34 of thepump or ejector 24. Thus the downward movement of the lever 27 effectsan ejecting stroke of the piston 34 ofthe syrup pump.

The packing gland 35 is threadedly secured upon the end of the cylinder36, of the pump and effects, a packin of the piston 34 with respect tosaid cylin er, by the compression of a suitable packing material 38, asshown vin Figure 15. -The pump 24 is provided with a terminal passageway39, extending transversely of the cylindrical poi'- tion 36 thereof andcommunicating therewith, and havingthe upper and Y lower threaded ends40 and 41 respectively. One or the other of these threaded ends isclosed up with a suitable plug or other threaded c osure 42, andthepacking 43, while' the Uil Ilm

other threaded end has 'attached thereto, the

ling nipple 47 of one of the check valves 48, a,

which are carried by, and communicate with the mixing chamber 49,.of thecontrolvalve 26, of our n ovel apparatus, as shown particu- 1n vFigures5, 9,v 11, 12 and 1'5. The.v

larly check valve 50, threadedly secured to thev tting 44, by means ofthe threaded end 51 is provided with the valve ball 52, which is adaptedto seatnpwardly against the valve ne l seat 53 when raised by a liquidflowing up- 'wardly. The check valve 50 is also provided with a nip le54, for the attachment thereto of one en of a' flexible hose 55, saidhose having its other end similarly attached '.to an outlet nipple 56 onthe corresponding syrup reservoir 14. Thus, upon drawing down anyone ofthe .operating knobs or handles 9, carried by the puter terminalsof vthecorrespondingoperating levers-27, inthe direction of the arrow 57, the"lower extension of the lever 27,

tlirou'gbv theconnectngrod 32, 'will aetaxate-v the iston 34 of thecorresponding pump 24, in t e direction of the arrow 58, thereby toforce out a fixed and predetermined quanti. ty of syrup fromthe`cylinder'36 thereof, t rough the transverse passageway 39 into thefitting 44. The syrup forced out by the piston 34, rais'es thecheckvalve ball 52 against the valve seat 53, thus preventing theretreat of the syrup tothe reservoir 14, and thereby causing the syrupto pass out throu h the nipple 45 and the corresponding iiexillc hose46, into and through the corresponding -iexible hose 46, into andthrough the corresponding check valve 48, into the mixing chamber 49, ofthe control valve 26.

The check valve 48, shown particularly in Figures 11 and 12, consistschieiiyV of the valve member 59, of any suitable shape, such as thespherical valve ball shown in the figures, carried by the valve stem 60,and held against the seat 61 in a direction outwardly of the mixingchamber 49, bym/cans of the helical compression spring 62, interposedbetween the spring seat 63, on the end of said valve rod and thestationary spring seat 64, carried by the casing 48 of the check valve.

Upon the reverse stroke of the piston 34, into its normal position,shown in Figure 15, the syrup from the corresponding tank 14, gravitatesdown into the cylinder 36 and the passageways interconnecting it withsaid cylinders 36, and completely fills the same. Thus, with eachoperating stroke of the lever 27, a given and predetermined uantity ofa. corresponding syrup is forced into the mixing chamber 49. The mixingchamber 49 is provided with the discharge nozzle 65 and the gravitycheck ball 66, seated upon 'acorresponding valve seat 67, whereby thecharge `of syrup forced into said mixing chamber'49 will be retainedtherein, unt-ilv the valve ball 66V is raised from its seat, by thedischarge of the carbonated. water into said mixing chamber underconsiderable pressure and hence with considerable force. as will bebrought out more in detail hereinafter.

The control valve 26, as will be seen particularly in Figures 11 and 12,and Figures 16 to 24 inclusive, consists of a housing 68 having a seriesof threaded openings 69 in the periphery thereof, for the reception ofthe threaded ends 70 of the series of check valves 48, through which`the various Syrups are delivered to the mixing chamber 49, within saidhousing 68. The o ening 71 is provided in one end of the cylin ricalcasing or housing 68, for 'the reception of the rotary valve stem 72.The outer projection or boss 74 having an enlarged opening internallythreaded, is adapted to receive a. suitable packing material 75, and thecorrespondingly threaded packing gland 73 adapted to compressV saidpacking material, thereby to ,68 of t make a .perfect sealing jointbetweeii the said valve stem 72 and the opening 71. The rotaryvalveportion or disc 7 6, carried ri idly by, and preferably formedintegral, wit the valve stem 72, is seated snugly and is journalledwithin the corresponding annular opening 77 in the other end of thecasing e control valve 26, in such a manner that the cylindricalperiphery 78 of the valve disc 76, contacts throughout its entirecircumference, over part of its width, with said annular openin 77.

The open end of te casing 68 is provided with a pair of guides or lugs79 projecting horizontall therefrom and having the right angle mem ers80, which are provided with suitable threaded openings 81. A stationaryvalve` block 82, containing the stationary ports of the valve, isprovided with suitable channels 83 betweena pair of parallel guideways84, on each side, which channels are adapted toreceive the guide lugs79, thereby accurately and rigldly to position the valve block 82' withvrespect to the rotary valve disc 76. The face 85 of the valve block 82is recessed slightly as shown in Figures 12 and 24 `and isthus adaptedto receive and retain a suitable leather packing disc or plate' 8 6,having a series of openings corresponding to and coincidin wlth theports in the face85 of the valve lock 82, which plate thereby acts as aacking medium between the stationary an the rotary ports of 'the controlvalve.

In order to retain the stationary valve block 82 in position Vandpressed tightly against the face 87 of the rotary valve disc 76, a yokebar 88 is secured to the right angle projections 80, by means of thebolts 89,.which yoke is provided with a set screw 91 threaded throughthe center of the yoke and adapted to enga e and bear against the centerof the, valve block, therebyv to exert an even pressure upon said block,and thus to force the same against the face of the rotary valve disc 76..The collar 92 preferably formed integral with the valve stem 72, isbutted up against the inner wall of the valve casing 68, therebypreventing any axial movement of the valve disc 76, due to the pressureof the set screw 91.

The carbonating battery 13 is disposed within the refrigerator chamber12, thereby to cool the water as it is being carbonated, so that it mayabsorb the maximum amount of gas. The refrigerator chamber 12, as

mentioned above, may be used in any one of two ways; namely, it may beused mainly for a refrigerating medium through which water is passedfrom an extraneous source, in which case the chamber'may be filled withice and salt, brine or any other refrigerayting medium; while onl theother hand it is equally practicable, and under certain conditions moredesirable, to utilize the chamllU ber 12, both-`as a refrigeratorchamber, as well as a reservoir for the water to be used in thecarbonating process. In thislatter case the chamber 12 is filled withpotable water to a substantial height and then a suiicient quantity ofpure and wholesome ice is added. 'The water used in the carbonatingprocess is then drawn in to the carbonating battery 13 by suction, fromthis mixture of ice and water Within the chamber 12 and immediatelysurrounding the carbonating battery. l

The carbonat-ing battery 13 consists of a lower manifold 93, the uppercover plate 94, a series of upright and preferably cylindricalabsorption chambers 95, 96 and 97 interposed between said manifold 93and said cover plate 94 and a mixing chamber 98 carried at the end ofsaid manifold, for the purpose of premeasuring a quantity of carbonatedwater, to be dispensed with each operation of the apparatus. The waterto be carbonated, is drawn either from an extraneous source such as thecity water main, or directly from the chamber 12, surround- -ing theabsorption battery 13, through the inlet opening 99 at one vend of themanifold 93. The Water is, moreover, drawn into said inlet 99 by suctioncreated intermittently within the chamber 97, and entirely independentlyof outside pressure, as will be described more in detail hereinafter, inconneet-ion with the detailed operation of the main control valve 26.

The valve 26 of our novel construction,

l shown particularly in Figures 5, 9, 11, 12 and 24, is Inounted upon orsecured to the frame' member or end plate 22 in any suitable vmanner,not shown in the drawings. The valve block 82 is provided with thefiveinlet ope-nings or passageways 111 to 11-5 inclusive, to the outerterminals of Which are attached the respective pipes 101 to 105inclusive, and the inner ends of `which terminate in the stationaryports 121 to 125 inclusive, iny the face of the valve block. Astationary relief port 128 is also provided in the annular opening 77 of-the casing 68 ofthe valve. By means ofthe series of pipes 101 to 105linclusive, the stationary port 121 is thus in constant and directcommunication with the gas storage tank 11; the port 122 is connectedwith one end of the manifold 93 of the absorption or carbonating battery13; the port 123 is connected with the inlet end of the absorptionbattery; the pipe 104 is connected with the top of the measuring chamber98; while the pipe 105 is connected with the manifold 93, intermediateof the measuring chamber 98 and the series of absorption chambers 95.The relief port 128 opens directly into the atmosphere, through thepassageway 118, as shown particularly in Figure 12. 4

vThe rotary or disc portion 76 of our novel after.

The operation 'of our novel'control valve valve is provided with asecond series of ambulatory or 'movable ports 131 to 137 inclusive inits face 87, contiguous to the face 85 of the valve block 82, and theport 138 in the peripheral surface 78 thereof, corresponding to the port128 inthe valve casing 68, as shown in Figures 12, 17 19, 20, 21, 22 and23. The rotary or disc portion 76 of the valve is further provided witha series of passageways 141, 142, 144,146, 147 and 149, interconnectingthe various ports in said disc in the manner shovvnparticularly inFigures 19 to 23 inclusive. In the Figures 16 and 17 and Figures 18 and19 there are shown the relative positions of the ports and passagewaysof the stationary and rotary portions of the valve in the open andclosed positions thereof respectively, which two positions areapproximately 45 degrees aparts, as indicated by the line 148. Thus inthe normal, inoperative, closed or off position of the valve 26, the,gas tank 11 is connected through the pipe 101, the stationary port 121,the movable port 131 the passage-way 141, the movable port 133, thestationary port 123 and the pipe 103, with the upper end oftheabsorption chamberv 97, at the entrance end of the carbonating battery13. Similarly the ports 132 and 135 are interconnected by means of thepassageway 142, as shown particularly in Figures 17, 19 and 22, whilethe ports 136, and 137 are connected by means of the passage-ways 146and 147, to an axial passage-way l149 extending into the valve stem 72,and communicating with a series of radial discharge v openings 150. Itwill here be noted'that the passage-way 146 joins the axial passageway149, a slight distance behind the point where the passage-way 147connects with said axial passage-way, so that the fluid passingtherethrough, will pass the junction point of the passage-way 146 andthe axial v I passage-way 149, with sufficient velocity as to create asuction in the passage-way 146. This suction or jetting action of thewater ypassing through the passage-way 147, upon the passage-way 146 isutilized to create' a suction within the first absorption chamber 97 ofthe carbonating battery 13, when the valve is in thel open or operativeposition,

thereby to draw in a fresh supply of water, independently of thepressure of such water, as will be described more in detail hereinis asfollowsz--In the normal, closed or off, position of the valve disc 76,that is, inthe position shown in Figure 17 relative to the stationaryvalve block 82, as yshown in Figure 16, the gasV tank 11 is connectedthrough the pipe 101 and the stationary port 121, the movable port 131,the passage-way 141, the port 133,"the stationary port 123, and the pipe103; to lthe first absorption thereof, forces the water within thechamber 97, into and through the manifold compartment .153 and throughthe upright spray pipe 154, causing it to raise the ball chec valve 155and thus forcing it out through the upper perforated end of thedispersing funnel 156 at the top of the spray pipe 154, into the secondabsorption chamber through 'which thewater, admixed with gas,

descends in the form of spray through theA screen 157, thus causing arapid absorptionof the gas by the water. The water thus continuesthrough the following absorption chambers 95 in a like manner, passingsuccessively through the series of similar manifold compartments 158 andthe corresponding series of upright spray tubes 159, posi-` tionedcentrally with respect to said absor tion chambers 95, in a manner shown1n Figure 14, and provided with u per perforated ends 160. Each of the asorption chambers 95 is similarly provided with the screen 161 tofacilitate the rapid absorption of the gas by the water. The lowermanifold 93 is further provided with the compartments 162 and 163, andhas mounted thereon a measuring chamber 98 in. such a manner that itcommunicates freely with the last compartment 163, while it communi-Cates-with the compartment 162 throughfa valve seat 1.64, uponl which isseated a ball check valve 165, thereby to limit the passage of the waterfrom the compartment 162 into the measuring chamber 98. The pipes 102,

104 and 105. are connected, in a manner shown in Figure 14, with thecompartment 163, the-top of the measuring chamber 98 and the compartment162 respectively, there-A .by establishing communication between thesame and the stationaryports 122, 124 and 125 respectivel There isfurther provided a checkvalve all 166, normally carried by a; retaineror basket 167, adapted Y.to seat against the upper entrance or oen1ng168 and to be raised bv the liquid in e measuring chamber 98,thereb to prevent the exit "of such liquid throng the pipe 104, but yetto permit the passage of as throughthe same pipe, as w'ill be descri edmore 1n detail hereinafter.

The charging or carbonating operation,

' as described above, takes place during the oiv or closedposition` ofthe valve, by-

the direct -action lof the lgas from the tank 11 .u on the watercontained and trapped within the first absorption chamber 97. In thisoip position ofthe valve, shown in Figures 16 and 17, the stationaryports 122 and125 are interconnected by means of the movable ports 132and 135 and the passageway 142, thereby establishing an equilibrium ofpressure between the compartments 162 and 163; While ythe port 124communicates with the movable port 134 and hence connects the measuringchamber 98, through the passage-way 144 and the movable port 138 withthe stationary port 128 and the passage-way 118, with the atmosphere. Inthis position any gas contained within the measuring chamber 98 isthereby relieved through the passage-way 118 since the force ofthe gasalone passing through the open- 96, ing 168 and the pipe104 is notsuiiciently strong to raise the ball check valve 166. Thus, as the gasin the measuring chamber 98 is displaced bythe carbonated water, urgedby the pressure of the gas in the absorption chamber, vit rises until itraises and seats said ball 166 upwardly, against the exit opening 168,thereby shutting of the measuring chamber 98 from the relief passage-wayand opening 118. Thus, agiven `quantity of carbonated Water is nowcontained and retained within the measuring chamber 98v during theoii:', closed or inoperative position of the valve.

Upon turning the valve, however. into the operative, open or onposition.' shown in Figures 18 and 19. the stationary port 121,heretofore connected with thel absorption chamber 97, is shunted throughthe passage way 141 to the stationary port 124 and hence to Ythe top ofthe measuring chamber 98 fthrough the pipe 104. In this position`.moreover, the stationary port 125. shut of by the blank surface. in theface of the valve disc 76, while the stationary port 122 com.-municating'withy the pipe 102 and the com-V partment 163 in the manfoldv93', is met by the .port 137 and connects through the passage-way 147with the axial passage-way .149' andr hence with the radial dischargeAopenings 150. Thus, the pressure of` the gas from the tank ,11, actingupon the surface of Vthe Water in the-measurlng chamber 98. forces thesame lout through'the compartment 163 and the pipe 102 out through thepassage-ways 147 and 149' and the disf charge openings 150, into themixing chamber 49; theball check valve 165 preventing the retreat ofthewater from the measuring chamber 98 back into the compartment 162. Inthe open or operative position of the valve, moreover, the stationaryport 123,`1s connected through the movable p ort 136 and the passage-way146 with the axlal passage# way 149 at a` point slightly back of zthepassage-wayV 147 as brought out 1`n detail lll) hereinbefore and shownparticularly in 'Figure 23, thereby the suction or jetting actioncreated by the water passing through the passage-ways 147 and 149creates a suction within the absorptionchamber 97, suliicient to raisethe check valve ball 151 and to draw into said chamber a fresh supply ofwater. Upon again returning the valve into the normal position, shown inFigures 16 and 17, the cycle of operations is again commenced, that is,the gas remaining within the measuring chamber 98 after the displacementof the carbonated` water therefrom, is relieved through the opening 118.

a and the carbonation of the fresh charge of water is then carried onthrough the various absorption chambers until the measuring chamber 98is again filled completely with the carbonated water.

In ord-er to obtain the desired mixing of the syrupl and the carbonatedwater, it is necessary to deposit the syrup into the mixing chamber 49,substantially prior to lthe discharge of the carbonated water thereinto.

This is readily obtained by an adjustment of the relative positions ofthe dogs 28 and the pins 29 throughoutthe main shaft 25,

so that the main shaft will notbe operatively engaged by any of thelevers 27, until such levers 27 have actuated the corresponding pistons34 of the pumps 36 through the major portion oftheir stroke, so that thedischarge of the syrup into the mixing chamber 49 will precede thedischarge of the carbonated water thereinto; although the two dischargesmay overlap each other.

In lorderto effect an automatic return of the` levers 27 and theoperating knobs 9` anyone of several means may be resorted to. Thus,` ifdesiredfthe levers 27 may be provided with .lower horizontal extensions169, upon which may be adjustably mounted the counter weights 170located in any` suitable position by the set screw 171, as shownfparticularly in Figures 12 and 15. If desired, however, .the levers 27may be returned by the pendent counter Weights 172 supported by theiexible cords or chains 173 passing over the idler pulleys 174 and'engaging the levers 27 at a suitable point 175 as shown in Figure 7..Still another means of returning the levers 27, is shown in Figure 48,wherein a tension spring 176 is.

interposed between a suitable point 177 on said levers 27 and a fixedstationary support Inorder to deposit a new and unused cup 18 from theycup dropper 16 into the cup support 20 carried by the serving platform21, as mentioned hereinbefore, there is provided a rocker arm 179pivotally mounted 'upon the pivot 18() and having one arm 181 Y thereofin alignment with the actuating lever 182 of the cup dropper and havingits other arm 183 extending into 'operative alignment with an actuatingarm 184 carried rigidly by either the main shaft 25 or the valve stem72, which is a continuation thereof and which is coupled thereto bysuitable means such as the coupling ends 231 and 232. By this means theactuating lever or arm 182 will be turned in the direction of the arrow185 with the movementv of the main shaft 25, and by so positioning'thearm 184 as to engage said rocker arm 179 during the first part of itsmovement and by so proportioning the relative lengths of the arm 181,183 and 184, the cup 18 is released and deposited on the servingplatform beneath and in vertical alignment with the nozzle 65, beforethe valve disc is moved into the lfull open or operative position shownin Figure 19, hence, prior to the discharge of the carbonated Water intothe mixing chamber and prior to the discharge of the mixed beveragethrough said nozzle 65. As mentioned above, the serving platform 21 iscarried b the door 6, pivotally mounted upon the hinges 186 and providedwith the glass panel 187 so as to expose to view the cup positioned uponsuch serving platform. Suitable means may be provided for yieldablyretaining the door 6 in the closed position. Such means may consist of aspring, counter weights or the like. A vertical flange- 188 is furtherprovided, surrounding said platform 21 for the purpose of damming anyliquid that may be spilled or that may over-flow from the cup, and isfurther provided with a small drain pipe 189 in one corner of saidplatform 21 which extends.

'f ing of the mixed beverage produced within the apparatus' as`described above, there are provided a series of coin control devicesinterconnectedwith the actuatinflr levers -27 in such a manner as tonormally retain the same locked in the upper or inoperative position andto release the same only when a suitable coin is inserted into thecorrespondinv' coin slot 8. Thus, therel are provided suitable uprightlelongated apertures in .the frontpanel 3 of the cabinet, over which arefitted the plates 196 carrying the guide-ways 194. The guide-ways 194support and guide the 'upright slide 195, which is also provided with acorresponding movable coin slot 8. The slide 195 is provided with a slotor 'aperture 197 through which the operating' lever 27 passes, so thatthe slide 195 will CTI necessarily be l'drawn ldovs'nwardly in itsguide-way 194, when-the lever 27 is moved downwardlv during the -workingstroke of the same. hus, in order-to lock the operating lever 27 in itsuper position, suitable means is provided orf locking the slide againstthe downward movement. This lock comprises a catch 198 Bivotally mountedupon the slide 195 upon t and an upright rack 200 rigidl carried'by oneof the guide-ways 194 an having its teeth provided with substantiallyhorizontal edges 201 and lower upwardly inclined edges 202. The-slide195 also supports a co'in plate 203, shown particularly 1n Fi res 3 and4, which coin plate is'positioned irectly above the coin slot 196 and asmall auxiliary coin guide bracket also carried lby the slide 195. Thecoin plate 203 is-also provided at its farthermost edge with anvoverhanging and horizontal nose piece or support 205 adapted to enga ethe edge of the coin as it is passed throng the coin slotl 8 and therebyto retain said coin in a horizontal position. The catch 198 is furtherprovided with a downwardly extending linger 206 (projecting down belowthe coin plate 203 an adaptcd to oscillate to and fro in a directionparallel to the slide 195 within a slight recess 207 in one edge of saidcoin plate 203 adapt- I ed toreceive such finger l206. There is furtherprovided a second `tube rack 208 provided with teethv 209 and lowerhorizontal edges 210 and the upper inclined edges 211.l The spring 212,pivotally supported upon the pivot screw 199, is interposed between thecatch 198 andtheupper surface of the coin plate 203 in a manner shown inFigure 2, so as to retain said catch in operative enjgagernent with theteeth of the rack 200.

By this novel construction, as the coin is inserted into the coin slot8, it encounters the fingers 206, forces .the same outwardly against theforce of the spring 212 and thereby withdraws the catch 198 fromengagement with the teeth -of the-rack 200. As the coin is fully4inserted into the coin slot 8, moreover, thelinger 206, urged by theforce of the spring 212, moves the coin to one side inthe direction ofthe rack 208, thus forcing the -edge of the coin against such rack.'The' coin thus inserted, having withdrawn the catch 198 from engagementwith the rack 200, ermits the downward movement of the slide 195 andthus permits the operation of the lever `27 and hence of the dispensingapparatus. As the slide 195 is thus moved downwardly by the lever 27,the edge of the coin carried by the guide bracket 204 and the nose.piece 205, successively engages each of the teeth 209 of therack 208 1nits downward travel, and since the lower edges 210 of said teeth aresubstantiall horizontal, it will interlock vwith such e dges in such amanner as to prevent the sli e 195 e pivot screw 199, l

and the lever4 27 from being moved -upwardly andhence from beingreturned to its upper normal position beforethe lever has beenV moved.into its lowermost or operative position. Hence, after the slide haslbeen moved down to its lowermost position, that is, when the edge of thecoin has passed,v the lowermost tooth 209 and has passed the lower endof the rack 208 the coin is ejected from its I osition beneath the'coinplate 203 by the 1 orce of the finger 206; `The coin being thus the coinslot 196.v Suitable means may be provided for-receiving the'coins asthey are ejected from beneath the coin plate 203, such not being shownin the ydrawin s.

In order further to lock any particu ar opera-ting lever 27 and knob 9in an inoperative position and to prevent the insertion of a coin intothe corresponding coin slot 8, when the'v correspon-ding syrup,reservoir 14 does not contain a suiiicient quantity of syrup to producethe beverage, there is provided novel l syrup control locking meansshown particularly in Figures 2 and 10. Thus, as shown vin Figure 2,there is provided a dog' 213 carried by a vertical sliding rod 214,guided by suitable guides215, whlch sli-ding rod is extended outhorizontally as at 216 and is,

provided with a second vertical sliding portion- 217 extending into thevcorresponding syrup tank 14 and guided by the guides 218.

vThe vert-ical slide 217, carrying a oat 219 at the lower extremetythereof,`which in its uppermost position, and hence in: the uppermostposition 4of the dog 213 is in close proximity to the bottom of thereservoir 14. Thus, so long as the level of the syrup 220 within thetank 14 is above the predetermined low level, it will retain the float219 and hence the dog 213 in the raised position shown in Figure 2.lWhen, however, the level of the syrup falls below the predetermined lowlimit, tliedog 213 is lowered into a position between .the'f edge 221-of the catch 198 and the straight edge 222 of the rack 208.

In this drawn osition, thef catch can not be withinserted 'into thecoinslot 8, being obstructed by the finger 206. Upon refilling oftheparticular reservoir, the rod-219 and hence theI` rom engagement withthe teeth'ofthe rack 200 and hence the coin can not be over, theoperation of the apparatus controlled by such device is limited to acoin of the proper denomination, as determined by its dimensions. Thus,if a coin of a smaller size is inserte-d, it will either fall throughwithout being retained by the nose piece 205, or if it is retainedbeneath the coin plate 203 by the nose piece 205 and yet falls slightlyshort of the required diameter, it will not entirely clear the catch 198from the teethof the rack 200 and therefore will not release the slide195. On the other hand, if the coin is too large it will, naturally, notenter the coin slot, which is purposely made of exact size.

In Figure lOthere is shown almodified form of a float controlled lockingdevice' for locking the slide 195 in an inoperative posi-` tion and forpreventing the insertion of a coin into the coin slot when the level ofthe syrup within the tank 14 is below the pre determined low limit. Inthis modification the float 223, upon the lowerend of the rod 224, iscarried by one end of the rocker arm 225 pivotally mounted at the point226. A p'awl 227 is-pivotally mounted at 228 in align-` ment with thecatch 198 and is interconnected with the other end of the rocker arm 225by means of the rod or cord 229, so thatl as the float 223l is loweredit raises the outer end 230 of the pawl 227, thereby moving said pawl227 down into engagement with the catch 198, thereby locking the same inan inoperative position in a manner similar to that sh'own in Figure 2and with like effect upon the insertion of a coin into the coin slot 8..
